Abstract

The oat crop has been neglected due to its use in limitation as a forage crop rather than a staple food in most of the countries throughout the world. Also it is more prone to foliar diseases, especially Helminthosporium leaf blight (HLB, syn Pyrenophora leaf spot) disease in the Punjab, especially Ludhiana region. It emerged as a new disease that can infect over 70% of the field resulting in up to forage yield losses of 50 per cent throughout. Hence, this study was conducted to evaluate the 167 germplasm lines for disease severity and its infection based on 1–9 scale through artificial inoculation of fungal spores. These lines were classified under four different clusters based upon infection with majority falling under cluster 2 and cluster 3 with infection of more than 50%. Lines ranged from being highly susceptible (more than 75% infection) to moderately resistant (22% infection). These contrasting lines were used in disease progression studies and also in hybridization programme to develop populations for future mapping studies. The contrasting lines were analysed for polymorphism using 220 SSR markers, of which 47 markers were polymorphic. Also the mapping for HLB resistance genes/QTLs is being carried out under the current ongoing research project, which will be the first research to map the resistance genes/QTLs in the oats throughout India and the world. Identified lines also can be used in future breeding programme to develop resistant cultivars.
